问题描述
我是android的新手，我有一个应用程序，在我的应用程序中，我正在获取用户的个人资料数据，在这里，在我的个人资料数据中，我正在获取用户先前设置的用户所在的州和城市，就像现在用户设置了以下状态并城市，而且我可以在微调器中显示该州和城市
I am new in android,I have one application,in my application i am getting user's profile data,here in my profile data i am getting user's state and city which user had previously set,like right now user set following state and city,and i am able to display that state and city in my spinner
{
"user_city": "Kolkata",
"user_state": "West Bengal",
}
现在的问题是，如果用户想要将状态从WestBengal更改为卡纳塔克邦，那么我需要显示所有状态并使用户更改，因此为此我有其他单独的Web服务来加载所有状态，并且我想显示所有状态状态与微调器处于同一状态，但现在的问题是我需要单击两次，然后才显示所有状态
Now issue is if user want to change state like from WestBengal to Karnataka,then i need to display all state and make user to change,so for that i have other separate webservice for load all state and i want to display that all state in same that spinner,but right now issue is i need to click two times then only it is showing all states

加载所有状态
class LoadStatess extends

private ProgressDialog pDialog;
private String test;
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(Profiles.this.getActivity());

pDialog.setIndeterminate(true);
pDialog.setIndeterminateDrawable(getResources().getDrawable(R.drawable.custom_progress));

}
protected ArrayList<HashMap<String, String>> doInBackground(
String... args) {
ServiceHandler sh = new ServiceHandler();
// Making a request to url and getting response
statedata = new ArrayList<HashMap<String, String>>();
String jsonStr = sh.makeServiceCall(STATE_URL, ServiceHandler.GET);
Log.d("Response: ", "> " + jsonStr);
if (jsonStr != null) {
try {
jsonObj = new JSONArray(jsonStr);
// state_list = jsonObj.getJSONArray(COUNTRY_LIST);
// looping through All Contacts
for (int i = 0; i < jsonObj.length(); i++) {
JSONObject c = jsonObj.getJSONObject(i);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(USER_STATUSS, c.getString(USER_STATUSS));
map.put(PRESET_TITLES, c.getString(PRESET_TITLES));
statedata.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
return statedata;
}
protected void onPostExecute(ArrayList<HashMap<String, String>> result) {
super.onPostExecute(result);
// pDialog.dismiss();
arrallstates = new String[statedata.size()];
for (int index = 0; index < statedata.size(); index++) {
HashMap<String, String> map = statedata.get(index);
arrallstates[index] = map.get(PRESET_TITLES);
}
// pass arrConuntry array to ArrayAdapter<String> constroctor :
adapterallstates = new ArrayAdapter<String>(
Profiles.this.getActivity(),
android.R.layout.simple_spinner_dropdown_item, arrallstates);
statespinner.setAdapter(adapterallstates);
statespinner.setPrompt("Select State");
statespinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
spitems = statespinner.getSelectedItem().toString();
System.out.println("PresetEVent selected" + spitems);
new Logincity().execute();
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
}
}
默认情况下，第一个屏幕显示
first screen by default get
然后，我单击加载状态它显示
then i click to load state it shows
然后我再次点击显示的唯一内容
then again i click the only it shows
推荐答案
另一个是要
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LoadListView();
}
private void LoadListView() {
try {
statespinner.setAdapter(adapterprostates);
} catch (Exception e) {
e.printStacktrace();
}
}
